What is the difference between 512e and 512n hard drives? 5

The difference between 512E and 512N hard disks is the physical sector.

Different, different performance, different ECC error correction codes.

First, the physical sectors are different.

E's hard drive: The 512e's hard drive has a physical sector of 4kb, which is 4096bytes.

N's hard drive: The 512N's hard drive has a physical sector of 512bytes.

Second, the performance is different.

E's hard drive: The 512e's hard drive doesn't need to read an additional 512-byte chunk chunk, and can read 4K bytes directly, so the performance is improved.

N drives: 512n drives need to read an additional 512-byte chunk and write it into a 4k byte sector, which makes performance slow.

3. ECC error correction codes are different.

N hard drives: 512N hard drives have 50 bytes of ECC error correction codes for each sector.

The first is a workstation-level hard disk, with high speed, high noise, high heat, fast speed, acceptable stability, high overall performance, fast read and write, but not cost-effective.

The second is a hybrid hard disk, with an SSD as a large-capacity cache, and the advantage of bursting fast and large cache is reflected when reading the same data many times, such as entering Warcraft for the first time and ordinary mechanical hard disks, the second time, and the third time is very soon after, and it is not very practical for ordinary players.

If you choose the first type of hard disk array for the server, if you need to choose the second type if you have to read data repeatedly, if you use both of them for personal use, it is mainly determined by the purpose of use.

512e and 512n refer to the read and write mode of hard disks, due to the emergence of 4KB physical sector disks, the original disks are all 512-byte sectors, and now the amount of data increases resulting in performance and capacity loss (because the sectors have ECC check).

This 512e and 512n refer to the case of this 512-byte sector, E is a native 4KB sector that simulates the 512 sector, and n is the native 512 sector.

The actual impact has not been calculated, there should be no impact, but the internal operation of the hard disk, after all, Seagate is only 6TB now has a 4KB model.

A solid-state drive (SSD) with a capacity (not an actual usable capacity) of 512.

512G refers to the capacity of the hard disk, the solid state drive is a new type of hard disk, the use of flash storage, the principle is similar to the USB disk, but the capacity is larger, the speed is faster, and there will be no noise when working.

If you don't have a lot of files stored and you're mainly playing games, then a 512g SSD is enough and worth buying. In addition to the incomparable speed of the HDD, the SSD does not have any mechanical moving parts inside, so it will not cause mechanical failure, and it is not afraid of collision, shock, and vibration, which is safer.

Advantages: Fast read and write speed: Flash memory is used as the storage medium, and the read speed is faster than that of mechanical hard disks.

SSDs do not use a magnetic head, and the seek time is almost zero. The continuous write speed is very amazing, and most SSD manufacturers will claim that their SSDs have a continuous read and write speed of more than 500MB s, and in recent years, NVMe SSDs can reach about 2000MB s, or even more than 4000MB s.

The speed of the SSD is not only reflected in the continuous read and write, but also the fast random read and write speed is the ultimate meaning of the SSD, which is most directly reflected in most of the daily operations. Related to this is the extremely low access time, the most common 7200rpm HDD has a seek time of 12-14 milliseconds, while SSDs can easily reach milliseconds or less.

512G SSD.

Solid-state drives.

It's an SSD, 512 is its capacity, and together it means a 512G SSD. Solid-state drives, commonly known as solid-state drives. Solid-state drives are electronic memory chips that use solid-state technology.

arrays made of hard disks. <

512G SSD. SSD is a solid-state drive, 512 is its capacity, and together it means 512G SSD. Solid State Disk or Solid State Drive (SSD), commonly known as Solid State Drive.

Solid-state drives are hard disks made with an array of solid-state electronic memory chips. The SSD consists of a control unit and a memory unit (flash chip, DRAM chip). SSDs are identical to ordinary HDDs in terms of interface specifications and definitions, functions and usage methods, and are basically the same as HDDs in terms of product shape and size (emerging, and other forms of SSDs are the same as SATA HDDs.

Completely different). It is widely used in military, vehicle-mounted, industrial control, first-class monitoring, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and many other fields. The operating temperature range of the chip is very large, commercial products (0 70) and industrial products (-40 85).

Although the cost is high, it is becoming more popular in the DIY market. Because the technology of SSDs is different from that of traditional HDDs, there are many new types of memory.

Manufacturers. Manufacturers only need to buy NAND particles, and then match the appropriate control chip to write the main controller**, and Tang Xiaonai will manufacture the SSD.

The difference between the two is that the former is two hard disks, if connected, you need to connect two interfaces, and if one disk is full in the later stage, it cannot be merged, while the latter is a large capacity, partitions, you can also adjust each other, and if you buy 1TB directly, it is more cost-effective.

There is no difference in capacity.

Two 512s can be grouped raidBetter performance.

Two 512 occupy two hard disk interfaces.

So if you have money, you still go directly to 1TBConvenient.

Hello, 1TB means HDD, 1TBSSD means SSD, and the types of HDDs are different.

Ask what does 16G+1TBSSD mean?

Q: What is the difference between an HDD and an SSD?

Differences between HDDs and SSDs:1HDDs are larger and take up more space than SSDs.

2.SSDs read and write faster than HDDs,** more expensive than HDDs. 3.

There is a motor and fan inside the hard drive, which dissipates heat a little better.

The number of hard disks is different between the two.

The former has two hard disks, and two hard disks need two interfaces.

The latter generally refers to the capacity of 1 hard disk.

There are also some differences in performance and function, which are not affected by ordinary users. (Used to turn on the disk array).

The capacity of the two is the same, the difference is that the former needs to provide two interfaces and occupy space.
